    What to do if shielding gas is not flowing in my Daihen WB-M500?
    • C
      Christopher SantosAug 19, 2025
      If the shielding gas isn't flowing, there could be several reasons: * The gas cylinder valve might be closed. Make sure to open it. * The gas cylinder pressure could be too low. Replace the cylinder. * The external input settings might be incorrect. Check the settings of internal functions F29 to F32. * The external input cables might be disconnected or short-circuited. Inspect the cables connected to the external input terminal block and repair or replace them if necessary.

    Why is the arc unstable on my Daihen WB-M500?
    • S
      smaldonadoAug 21, 2025
      An unstable arc can occur due to several factors: * Incorrect welding mode settings. Verify the settings for wire diameter, wire materials, and shielding gas. * Defective wire or wire feeding issues. Inspect the wire and wire feeder for any problems. * Incorrect voltage detection cable connection. Ensure the voltage detection cable is properly connected. * Noise in the voltage detection cable. Try adjusting the arc characteristics to the plus side.

    What to do if shielding gas does not stop flowing in my Daihen WB-M500 Inverter?
    • S
      Stephanie ThompsonAug 23, 2025
      If the shielding gas continues to flow, it might be due to: * Incorrect external input settings. Verify the settings of internal functions F29 to F32. * Disconnected or short-circuited external input cables. Inspect the cables connected to the external input terminal block and repair or replace them if necessary.

    How to fix Daihen WB-M500 when wire is not fed (no error code)?
    • S
      Scott RamseyAug 26, 2025
      If the wire isn't feeding and no error code appears, consider these possibilities: * The pressure roll of the wire feeder might have come off. Correctly set the pressure roll of the wire feeder. * There could be an issue with the wire feeder cables. Check the cables for any abnormalities.

    What to do if I can't set the current/voltage on my Daihen Inverter?
    • J
      John GloverAug 28, 2025
      If you're unable to set the current or voltage, it could be due to: * The automatic machine mode being selected. Check that the setting of internal functions F4 is correct. * An analog remote control being connected. When an analog remote control is connected, its settings take priority. * A broken encoder. The printed circuit board PCB2 (P30086R00) needs to be replaced. Contact your dealer.

    What causes blowholes when using a Daihen WB-M500?
    • A
      Anthony PetersonAug 30, 2025
      Blowholes can be caused by: * A problem with the shielding gas. Check the gas cylinder and hose for any issues. * A worn-out welding torch tip. Replace the chip.

    What to do if arc does not generate even when the setting of welding conditions is correct on my Daihen Inverter?
    • L
      Linda JohnsonSep 1, 2025
      If the arc doesn't generate despite correct welding condition settings, check these: * A loose torch cable connection. Ensure the torch cable is securely connected. * A broken torch switch. Verify that the torch switch is functioning correctly.

    Why doesn't the mode change when I press the CRATER-FILL key on my Daihen Inverter?
    • B
      bcarterSep 3, 2025
      If the mode doesn't change when pressing the CRATER-FILL key, it might be because the internal function F4, F48 or F51 is set to "ON". Turn the settings to "OFF".

    What to do if the power LED switch does not light even when the power switch is turned on on Daihen Inverter?
    • J
      Joanne CarterSep 5, 2025
      If the power LED switch doesn't light up when the power switch is on, the primary power source might not be supplied. Ensure the primary power source is between 340 to 460 V.

    What does it mean when the "Temperature WARNING" LED lights on my Daihen WB-M500?
    • J
      Jason MaldonadoSep 7, 2025
      If the "Temperature WARNING" LED lights up and an error code is displayed, the protection circuit has been activated due to a temperature error. Leave the Inverter untouched (with the power on) and let the cooling fan run for at least 10 minutes, then turn off the power. Afterward, clean any dust inside the welding power source.
